Rain fade is most susceptible in which band?

Explanation:
Rain fade is the attenuation of a radio signal caused by raindrops absorbing and scattering the energy. Attenuation increases with frequency, because higher microwave frequencies interact more strongly with raindrops. Among these bands, Ka-band operates at about 26.5 to 40 GHz, which is higher than Ku, C, and S bands. That higher frequency means more loss through rain, so Ka-band experiences the most rain fade. S-band and C-band are at lower frequencies and are less sensitive to rain; Ku-band is affected, but not as severely as Ka. So the band most susceptible to rain fade is Ka-band.
